I believe that some CPR folks , if they do their due diligence and get grader notes that reveal "pressable" flaws will pay a premium... outside of that, it is just a "myth" from what I have seen (bid on, bought, etc)....
sure there are examples of old label selling higher, but there are as many examples of new labels selling more.... it still should go back to the "buy the book, not the label" if you are purchasing as a collector...
if you are purchasing as a reseller, then your milage may vary
Thanks Rick. Your insight is helpful as always. (thumbs u
